Witkin State Law Library
The Witkin State Law Library offers an extensive collection of primary and secondary legal sources with a focus on California law. Primary sources from California’s beginnings aid the Legislature and state agencies in tracing legislative or regulatory histories, and practice guides and court briefs aid lawyers and those proceeding pro se. Our rare and frequently consulted collections include virtually all California legislation dating back to 1867, superseded California Codes, and the California Code of Regulations Supplement and Notice Register. Extending beyond California, we have materials relating to other states, federal legislation, and even historical and international law.
